Abstract:

Perovskite oxides comprise large families among the structures of oxide compounds, and several perovskite-related structures are also known. Because of their diversity in chemical composition, properties and high chemical stability, perovskite oxides are widely used for preparing solid oxide fuel cell (SOFC) components. In this work a few examples of perovskite cathode and anode materials and their necessary modifications were shortly reviewed. In particular, nickel-substituted lanthanum ferrite and iron-substituted strontium titanate as cathode materials as well as niobium-doped strontium tit

Abstract:

The synthesis conditions and mechanical performance of alite-rich cement clinker were investigated by the orthogonal test method. Sintering temperature, sintering time and contents of strontium oxide or strontium sulfate were taken as the influencing factors for the orthogonal test. The experimental results show that the optimal sintering temperature and sintering time are 1450 °C and 60 min, and the best strontium oxide or strontium sulfate content in the clinker is 1.5% and 0.5%, respectively. The doping of strontium oxide or strontium sulfate can promote the formation of alite mineral. That

Abstract:

Dental implants can be made of various materials, and amongst them, titanium and titanium alloy were the materials of choice for dental implants for many years because of their biocompatibility. The two alloys have a high level of biocompatibility, a lower modulus of elasticity, and better corrosion resistance than other alloys. Thus, they are frequently utilized in biomedical applications and mostly replace stiff fabrics. The latest advances in a new strontium oxide–cp titanium composite alloy are the main topic of this research. With regard to biomedical applications, additions of strontium

Different phases present in the sintered samples were determined from X-ray diffraction investigation and the distribution of different phases in the microstructure was assessed from scanning electron microscopy study. It was observed that the dielectric properties of BST were modified significantly with nickel oxide doping. These ceramics held pro

Abstract:

The thermal stability of the high-pressure phase 8-coordination of oxygen in Cerium-doped Strontium oxide (SrO:Ce) phosphors was investigated in this study. Due to the tendency of Strontium oxides 6-coordination of oxygen to react with moisture, high thermal and chemical stability is required for commercial applications. Eight-coordinated SrO:Ce phosphors were synthesized by sintering in a reducing atmosphere, and their thermal stability was examined using X-ray diffraction (XRD), photoluminescence (PL), cathodoluminescence (CL), and X-ray photoelectron spectroscopy (XPS). The results show tha

Abstract:

Perovskite-like oxides based on lanthanum-strontium ferrites are considered promising electrode materials for use in various types of fuel cells, and the strategy of modifying these materials by partial substitution of iron with highly charged ferroactive cations has proven to be an effective way to increase their chemical stability. In this paper, for the first time, the results of a study of the permeability of microtubular oxygen membranes based on La0.5Sr0.5Fe1 – xNbxO3 – δ oxide are presented. The activation energy of oxide bulk diffusion (20±4 kJ/mol) was found.

Abstract:

Strontium hexaferrite is one of the very important categories of magnetic materials with a wide range applications. One of the very critical parameters in the high temperature method of production of this material is molar ratio of iron oxide to strontium oxide. Although there could be found some reports on the effect of this parameter on the physical properties of the material in the literature but there are very few investigations about the role of this factor on the reactions occurred in the process. In this work the effect of different molar ratios of precursors on the reactions carried ou

The addition of La2O3has been found to play an important role in crystallization of perovskite (Pb,Sr)TiO3as a solid solution phase. Also, it causes a change in the surface morphology of the fined crystallites of the major phase. Differential thermal analysis (DTA) shows only one exothermic crystallization peak, which shifts towards higher temperature with increasing amount of strontium ox

The strength of XPS imaging lies in its ability to (i) locate small patterns on sample surface, and (ii) inform, with micrometric lateral resolution, about the chemical environment of the elements detected at the surface. In this context, strontium-based perovskites appear to be well-adapted for such photoemission experiments thanks to their tunability and variability. These functional oxides have great potential for emerging optoand microelectronic applications, especially for transparent conductive oxide.

Developing alternative electrodes that are devoid of Sr is very important for long-term operation of SOECs. In this work, we synthesized and evaluated properties of La2NiO4-based co

Abstract:

The interface of two materials having different work function leads to the development of space charge, resulting in the change of defect equivalence and hence the change in the charge carrier concentration. Another possibility lies in the formation of strain at the interface resulting in the change of the mobility of ionic charge carriers. If we can use these effects for the enhancement of ionic conductivity, introduction of hetero-interface is a potential guideline for designing new ion conduction in solids.
